Definitions

• the intensifier is a primary or secondary amide of a dicarboxylic aliphatic acid or anhydride wherein one carbon atom in the chain connecting the two acid groups bears an alkyl or alkenyl radical containing at least six carbon atoms.
• the method gives better whiteness and more particularly prevents the re-deposition of dirt.
• the invention relates to an improvement to dry cleaning of textiles, i.e., the washing of textile fibres or articles with non-aqueous solvents.
• the invention relates more particularly to the use of a novel kind of adjuvants which improve cleaning and give more thorough bleaching or cleaning.
• the invention relates to the novel kind of drycleaning intensifiers and to baths containing the aforementioned adjuvants.
• Dry cleaning is an activity which has recently become widely extended and which uses large tonnages of solvents.
• the solvents are mainly chlorinated hydrocarbons, more particularly perchloroethylene and trichloroethylene which, owing to their nonflammability and other advantageous properties, have become the main solvents used in this branch of industry. Whatever solvent is used, however, i.e.
• the solvent does not usually produce adequate cleaning by itself; it is well known to add surface-active agents soluble in the given solvent to the cleaning bath, For example it has become conventional to add agents such as the following to the solvents: amine alkyl-aryl sulphonates, ethoxylated derivatives of aliphatic amines or alcohols, or alkyl-polyethoxy-phenols.
• the invention provides a novel kind of adjuvants for dry-cleaning baths which substantially improve the degree of cleaning compared with that obtained with conventional surface-active agents.
• the novel adjuvants are particularly effective when used together with conventional surfactants in the presence of a small proportion of water in the solvent; the resulting cleaning is much more thorough than could be obtained with either of the additivesi.e., the adjuvant according to the invention and the conventional agent-if used alone.
